Morespecifically, the speaker 30 may be positioned in a lower portion of thesupport body 21 inside the support body 21. The speaker 30 may outputsound to correspond to images displayed on the display module 10.However, the speaker 30 may output sound independently even when thedisplay module 10 is in a power-off state. Also, the speaker 30 may beconnected to an external device such as a mobile device 2 in a wired orwireless fashion to output sound reproduced by the external device.

The mounting device 100 may support the mobile device 2 to mount themobile device 2 on the display module 10. The mounting device 100 may becoupled to the display module 10. The mounting device 100 may beremovably coupled to the display module 10, although not limitedthereto, which will be described later.

The mobile device 2 may be a kind of an external device, and mayinclude, for example, a smart phone. Recently, with widespreaddissemination of mobile devices, attempts for using mobile devices byvarious methods are being made. Representative examples of such attemptsare mirroring of outputting sound output from a mobile device and imagesdisplayed on the mobile device through a display module, and casting ofoutputting content being outputting from a preset application of amobile device through a display module. To use such mirroring orcasting, the mobile device 2 may need to be paired with the displayapparatus 1. According to a concept of the disclosure, the mobile device2 may be paired with the display apparatus 1 through various methods,which will be described later.

Recently, many people photograph themselves through cameras to producecontents. Also, many people check their gestures by using cameras whenpracticing dancing or doing exercise. As such, a user's need for amirror mode that uses screens of a camera and a display as mirrors, isincreasing. However, to provide the mirror mode, a camera needs to beinstalled in a display apparatus, and when a camera is installed in adisplay apparatus, invasion of privacy and security issues may becaused. Also, due to an increase of cost for installation of the camera,the marketability of the display apparatus may deteriorate.

According to a concept of the disclosure, the display apparatus 1 mayprovide a mirror mode without installing a camera. To provide the mirrormode, the display apparatus 1 may include the mounting device 100. Bymounting the mobile device 2 including a camera module 2 a on themounting device 100 and pairing the mobile device 2 with the displayapparatus 1, a mirror mode may be provided. Because the mobile device 2generally includes the camera module 2 a, the display apparatus 1 mayprovide the mirror mode by using the camera module 2 a of the mobiledevice 2. As such, by using the camera module 2 a of the mobile device 2which is an external device, a cost increase of the display apparatus 1,which may be caused by installation of a camera, may be prevented inadvance. Also, by mounting the mobile device 2 on the mounting device100 as necessary, invasion of privacy and security issues, which may becaused by the display apparatus 1, may be prevented in advance.

Referring to FIG. 2, the longer side of the display module 10 ispositioned in a vertical direction and the shorter side of the displaymodule 10 is positioned in a horizontal direction. Hereinafter, theposition of the display module 10 is referred to as a vertical mode.Also, it may be expressed that the display module 10 is at a firstposition.

Referring to FIG. 3, the display module 10 may be positioned such thatthe longer side is in the horizontal direction and the shorter side isin the vertical direction. Hereinafter, the position of the displaymodule 10 is referred to as a horizontal mode. Also, it may be expressedthat the display module 10 is at a second position.

A user may position the display module 10 to the vertical mode or thehorizontal mode selectively according to a screen ratio of images.

It is common for a display module to be fixed at a horizontal position.However, when a vertical image is displayed on the display module fixedat the horizontal position, no image is displayed on both side areas ofthe screen of the display module so that the screen fails to beefficiently used. To meet the latest trend of using both vertical imagesand horizontal images, a display apparatus capable of efficientlydisplaying various screen ratios is needed.

The display apparatus 1 according to a concept of the disclosure mayposition the display module 10 in the vertical mode when displaying avertical image, and position the display module 10 in the horizontalmode when displaying a horizontal image, thereby efficiently using ascreen display area 11.

The support device 20 may rotate the display module10 from the vertical mode to the horizontal mode or from the horizontalmode to the vertical mode.

The support device 20 may include a motor (not shown). The supportdevice 20 may use a driving force of the motor to rotate the displaymodule 10. Therefore, according to a concept of the disclosure, a usermay drive the motor (not shown), instead of manually rotating thedisplay module 10, to thereby automatically rotate the display module10.

According to a concept of the disclosure, the mounting device 100 maysupport the mobile device 2 although the display module 10 is positionedin the horizontal mode. In other words, the mounting device 100 maysupport the mobile device 2 such that the mobile device 2 is notseparated from the mounting device 100 even when the display module 10is positioned in the horizontal mode. Accordingly, the mobile device 2may be mounted on the display module 10 regardless of a position of thedisplay module 10.

A user may selectively position the display module 10 to the horizontalmode or the vertical mode, and the display apparatus 1 may provide amirror mode, mirroring, and casting in the horizontal mode or thevertical mode.
